Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
This European Standard is divided into two parts:
Part 1 General requirements, which are common to most transportable motor, operated tools (for the
purpose of this European Standard referred to simply as tools) which could come within the
scope of this European Standard.
Part 2 Requirements for particular types of tool which either supplement or modify the requirements
given in Part 1 to account for the particular hazards and characteristics of these specific tools.
Compliance with the relevant clauses of Part 1 together with this Part 2 provides one means of
conforming to the specified essential health and safety requirements of the Directive.
This European Standard follows the overall requirements of EN ISO 12100.
For noise and vibration, this European Standard covers the requirements for their measurement, the
provision of information arising from these measurements and the provision of information about the
personal protective equipment required. Specific requirements for the reduction of the risk arising from
noise and vibration through the design of the tool are not given as this reflects the current state of the
art.
Warning:
Other requirements arising from other EU Directives can be applicable to the products
falling within the scope of this standard.

modifies the corresponding clauses of EN 61029-1, so as to convert it into the European Standard:
“Safety requirements for transportable circular saw benches".
Where a particular subclause of Part 1 is not mentioned in this Part 2-1, that subclause applies as far
as is reasonable. Where this Part 2-1 states "addition", "modification" or "replacement", the relevant
text of Part 1 is to be adapted accordingly.
Clauses, subclauses, notes, tables and figures which are additional to those in Part 1 are numbered
starting from 101.
Clauses, subclauses, notes, tables and figures which are additional to those in IEC 61029-2-1 are
prefixed “Z”.
NOTE In this European Standard, the following print types are used:
-
requirements proper: in roman type;
test specifications: in italic type;
explanatory matter: in smaller roman type.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive.
For the relationship with EU Directive 2006/42/EC, see informative Annex ZZ, which is an integral part
of this document.

18 Stability and mechanical hazards
This clause of Part 1 is applicable except as follows:
18.1
Addition:
Circular saw benches shall be equipped with a guarding system, which cannot be removed without the
aid of a tool. This requirement does not apply to a top guard fixed to a riving knife.
18.1.101 Guarding above the saw table
18.1.101.1 Circular saw benches shall have a top guard for the crown and the front of the saw blade
that may be an adjustable guard, a self-closing guard or a combination of these. An adjustable guard
when adjusted shall remain in any position necessary to give the required protection.
-
For riving knife mounted guards:
For all intended saw blade diameters and all positions of the saw blade, the guard shall cover the
top and sides of the exposed saw teeth above a straight line between the guard mounting point on
the riving knife and the first cutting tooth at the top of the table with the saw blade in the vertical
position (an example is shown in Figure Z102). The maximum external width except a dust
extraction port, if any, shall be 40 mm.
-
For other top guards:
When mounted separately from the riving knife, but integral with the machine, the support for the
top guard shall not be in line with the riving knife.
The guard shall be capable of screening the top and both sides of the saw blade horizontally
between the riving knife and the table at the front of the saw blade, shall be adjustable from a
position 5 mm above the maximum height of cut down to the table and shall remain parallel with
the table. The maximum external width shall be 50 mm.
For tools that have the facility to tilt the saw blade, either an auxiliary guard shall be provided, or
the tool guard shall be capable of being fitted with an extension piece for use during angled
cutting. The guards or extension pieces shall be exchangeable without the aid of a tool.
18.1.101.2 The top guard shall be constructed from soft material (e.g. aluminium or plastic) which will
minimize damage to the saw blade should contact occur.
The guard shall be designed to bear against the smooth sides of the saw blade in order to minimize the
risk of damage to the guard. Either
-
the guard side walls shall have a thickness of minimum 6 mm or
-
the guard side walls shall be equipped with internal ribs on at least the lowest 3 mm of the side
walls providing a total thickness of minimum 6 mm (see Figure Z103).
If one side wall of a self-closing guard is made longer for bevelling, the 6 mm requirement does not
apply to the additional side wall portion.

EN
A self-closing guard shall automatically
a)
open by contact with the workpiece to be cut as it is moved towards the saw blade;
b)
remain in contact with the upper surface of the workpiece as it is cut, to screen both sides of the
saw blade at least down to the root of the teeth and at least between the upper surface of the
workpiece and the riving knife;
c)
return to the initial position, in contact with the top of the table, after the workpiece has moved past
the guard.
Compliance with 18.101.1, 18.101.2 and 18.101.5 is checked by inspection and by measurement.
18.1.101.Z1 The guard and its supporting system shall have sufficient stability to reduce the risk of
the saw blade making contact with the guard.
Compliance is checked, with no saw blade fitted, by the following test (see Figures Z104 a) and
Z104 b)).
-
For riving knife mounted saw blade guards:
While the guard is subjected to a load of 5 N at the front edge of the guard as defined in
Figure Z104 a), the maximum deflection shall not be more than 15 mm.
-
For separately from riving knife mounted saw blade guards:
While the guard is subjected to a load of 20 N at the front edge of the guard as defined in
Figure Z104 b), the maximum allowable deflection shall not be more than 8 mm.
18.1.102
Guarding below the saw table
18.1.102.1 Access to dangerous moving parts under the table shall not be possible at any depth of
cut and any angle of inclination of the saw blade.
Compliance with 18.1.102.1 is checked by using the test probe in Figure Z105.

If contact between the cross-cutting fence and the saw blade cannot be avoided, the part close to the
saw blade shall be made of a material that can easily be cut such as aluminium, wood or plastic.
The minimum height of the guiding surface of the fence shall be 30 mm or the maximum cutting
capacity, whichever is the smaller.
Where the fence passes beneath the saw blade top guard the maximum height of the fence shall not
exceed 12 mm.
Compliance is checked by inspection and measurement.
18.1.106 Flanges
The outer diameter of the contact surface shall be not less than 0,2 times the saw blade diameter. The
overlap a of the clamping area of the two flanges shall be at least 1,5 mm wide as specified in
Figure Z112.

Connection ports for external dust collection equipment, if any, shall be directed away from the
operator.
Compliance is checked by inspection.
It shall not be possible to gain access to the saw blade through the dust outlet opening.
Compliance is checked by applying the test probe of Figure Z105.

18.1.Z101 Push accessories
A push stick or push-block handle shall be provided. The surface that may contact the saw blade shall
be constructed from shatterproof materials capable of withstanding the pressure necessary to feed the
workpiece. The material shall be such so as to not give rise to danger in the event of contact between
the saw blade and the push stick, e.g. wood or plastic.
The minimum length of push sticks shall be 400 mm or the length of the table, whichever is the less.
See Figure Z113.
Compliance is checked by inspection and measurement.
18.3
Modification:
Compliance of the requirement in Part 1 is checked by the following test.
The tool shall be placed on a horizontal fixed chipboard with smooth surface.
When a push force of 100 N is applied to the front edge of the saw table in the direction of the
workpiece feed, the tool shall not move or start to tip.
The force is then increased to 300 N or until the tool begins to move horizontally, whichever is
achieved first. During this test, the tool shall not tip over.
